[ Upstream commit 51f93add36 ]
The frame_length_lines (0x0340) registers are hard-coded as follows:
- 4208x3118
frame_length_lines = 0x0c50
- 2104x1560
frame_length_lines = 0x0638
- 1048x780
frame_length_lines = 0x034c
The driver exposes the V4L2_CID_VBLANK control in read-only mode and
sets its value to vts_def - height, where vts_def is a mode-dependent
value coming from the supported_modes array. It is set using one of
the following macros defined in the driver:
#define IMX258_VTS_30FPS 0x0c98
#define IMX258_VTS_30FPS_2K 0x0638
#define IMX258_VTS_30FPS_VGA 0x034c
There's a clear mismatch in the value for the full resolution mode i.e.
IMX258_VTS_30FPS. Fix it by rectifying the macro with the value set for
the frame_length_lines register as stated above.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
